In view of the problems of poor mining safety, low recovery efficiency, high cost, low recovery rate and few recovery options in steeply inclined, extremely unstable thin to medium-thick ore bodies, especially there are no economically feasible mining options for low-grade resources of this type of deposit Difficult problem. The paper proposes a safe, high-efficiency and low-cost mining technology suitable for steeply inclined thin ore bodies-segmented empty field subsequent filling mining method combined with 3Dmine and ANSYS to establish a FLAC3D numerical model to obtain a stope production capacity of 180t/d and a loss rate of 7.40%, the expected effect of the dilution rate of 14.96%.
